C#设计模式之Builder生成器模式解决带老婆配置电脑问题实例

本文实例讲述了C#设计模式之Builder生成器模式解决带老婆配置电脑问题。分享给大家供大家参考，具体如下：

一、理论定义

生成器模式 又叫：建造者模式，它  可以 把一个 复杂的对象，分步骤创建。

二、应用举例

需求描述：话说发工资了，打算去岗顶百脑汇  给老婆配置一台电脑。
OK，坐着BRT，就出发了。
到岗顶，一美女扑面而来，面带微笑：先生，请问看中那个品牌，过来看一下嘛！
人家都开口了，盛情难却，就看下吧。

21.运行结果

22.总结

本来想把每个电脑配件再细化，发现工程很大，电脑 产品的属性很多，所以只列出2个字段。

附件里面包括了程序源码。也包括其他项目的测试，有控制台，有web。

附：完整实例代码点击此处本站下载。

希望本文所述对大家C#程序设计有所帮助。
